Pedro Dinis — Thu, 21 Jun 2007 03:40:32 GMT

Then you need to change your rule:
obj/Modelo.o: Modelo.cc Modelo.h
$(CCC) $(CFLAGSCC) -c Modelo.cc -o $@

Oops you had some "..":
../obj/Modelo.o: Modelo.cc Modelo.h
$(CCC) $(CFLAGSCC) -c Modelo.cc -o $@

i did it like this

Modelo.o: Modelo.cc Modelo.h
$(CCC) $(CFLAGSCC) -c Modelo.cc
cp *.o ../../obj
rm *.o

../obj/Modelo.o:

../obj/Modelo.o: Modelo.cc Modelo.h
$(CCC) $(CFLAGSCC) -c Modelo.cc -o $@

is now calling g++ instead of aCC

[]-pedro:/home/pedro/MODELO_CC>make
g++ -c -o Main_Program.o Main_Program.cc

very strange

I'm not sure why you want to do it like this. This defeats total build avoidance. You should tell the compiler and make exactly where your files are and not have intermediate stages.

../obj/Modelo.o: Modelo.cc Modelo.h
$(CCC) $(CFLAGSCC) -c Modelo.cc -o $@

>is now calling g++ instead of aCC

I'm not sure why? Did you define CCC=aCC?

yes

CCC = aCC

i am using aCC with OCCI form Oracle

That should do it. I'm not sure if make -p would be of any help.

If you have gotten your answers, you should assign points and close the thread.
